Abstract

New materials, such as HDPE, that have not been in existence long enough to have demonstrated their longevity in the field, are naturally questioned as to their design life and suitability for infrastructure solutions. Plastics specialist, Dr Vasilios Samaras, explains that HDPE longevity, way beyond 50 years, can be demonstrated through scientific research. It should also be remembered that first generation HDPE pipes were installed over 40 years ago, and are still in use without any signs of fatigue.
